From: Monk Liu Date: Mon, 6 Feb 2017 08:46:36 +0000 (+0800) Subject: drm/amdgpu:divide KCQ mqd init to sw and hw X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=596c67d076a5ae0f2571cab9245ee76f6a6cf922;p=openwrt%2Fstaging%2Fblogic.git drm/amdgpu:divide KCQ mqd init to sw and hw sw part only invoked once during sw_init. hw part invoked during first drv load and resume later. that way we cannot alloc mqd in hw/resume, we only keep mqd allocted in sw_init routine. and hw_init routine only kmap and set it.
